An optical identification friend-or-foe (IFF) system for vehicles comprises an active cooperative identification friend-or-foe (ACTIFF) system wherein a responder optical head is located on each friendly vehicle. That responder optical head comprises a number of small panels arranged in an array with surfaces of adjacent panels being at an angle to each other, the outer surfaces of the panels being coated with laser paint designed to emit radiation at one or more selective wavelengths when subjected to a suitable interrogation pump beam. Those selective wavelengths form an identification code for a vehicle. In operation, an interrogating vehicle would transmit a narrow well-collimated infrared (IR) beam towards a target vehicle causing laser paint on the coated surfaces to emit the selective wavelengths when subjected to that IR beam. These wavelengths can then be detected by the interrogating vehicle for identification purposes.

[ The embodiments of the invention in which an exclusive property or privilege is claimed are defined as follows:] [12.] An optical identification friend-or-foe system for vehicles, the system comprising a narrow beam interrogation means and a narrow field-of-view detection unit directed in the same direction as said narrow beam located on an interrogation vehicle and a responder optical head mounted on a target vehicle, the interrogation vehicle having means to direct the narrow beam toward a target vehicle with the detection unit having means to detect one or more selective wavelength emissions from the responder optical head on a target vehicle, which emissions form an identification code for the target vehicle; the optical head comprising a number of flat surfaces coated with laser paint wherein the flat surfaces are arranged at an angle to each other with their coated surfaces facing outward, the laser paint being designed to emit radiation at said one or more selective wavelengths when subjected to a suitable infrared (IR) pump beam, the narrow beam from the interrogation means forming said pump beam causing the optical head to emit said one or more selective wavelength emissions when irradiated with said narrow beam.
